Obogashchenie Rud

The section “Ore Preparation” is represented by the article by А.А. Yatsenko, bringing up the subject of search for optimal shape of grinding bodies. The author proposes grinding media charge, chosen as a result of his observations of grinding balls wear. The article may raise an interest with a view to recommence the studies in that direction.

Among technological developments, an interesting study (the article by V.А. Sentemova, V.А. Dyubchenko) on the Thakhe deposit zinc-bearing iron ores preparation for metallurgical process stage (the only large magnetite ores deposit in Vietnam) is published. The physical-and-mechanical, as well as hydrometallurgical methods of zinc removal from concentrates proved to be inefficient. High-grade concentrates production for Direct Reduction of iron is recommended as most promising in the way of the deposit ores utilization.

Using high-informative Moessbauer spectroscopy and thermomagnetic analysis methods, the Lisakovskoye and Ayatskoye deposits’ brown iron ores concentrates magnetizing roasting products’ phase composition was studied (the article by А.А. Mukhtar et al.). The study permits to explain the reason for iron content increase in gravity-magnetic concentrate with its roasting over hydrocarbonic reducer.

Electromagnetic separator, described in the article by А.О. Mezenin et al., is designed for concentration of material with particle size below 75 microns. A vibrational fluidization effect, employed in this apparatus, lowers adhesion of fine particles and also decreases dry friction that hinders recovery of weak-magnetic particles.

The article generalizing the experience gained in the course of works related to the Udokan deposit and analyzing main design criteria for large-capacity processing plants will be useful for designing engineers (the authors – G. N. Smirnov, V. F. Baranov).

The issue is ended with a detailed report on the Plaksin Readings-2010 (the article by I.V. Shadrunova et al.): the discussed subjects are listed, promising developments are noted, the adopted decisions are presented.
